Results A total of 49 cases fit the inclusion criteria. Most were male (90%), with a median (IQR) age of 42.6 (39-46.7) years-old. Eighteen (36.7%) were or had been chronic infected by HCV. Among HBsAg+ patients, 19 (41.3%) were HBeAg+ and 13 (26.5%) were superinfected by the hepatitis delta virus (HDV). No differences were found in the distribution of CC genotypes when comparing patients with ...

transfusion-transmissible infections such as hepatitis b and hepatitis c are among the greatest threats to blood safety for transfusion recipients and pose a serious public health problem. the aim of this study was to assess the epidemiological aspects of hepatitis b and c in kazakhstani donor's blood over the period 2000-2011.the data were obtained from the annual reports of the republican blo...

conclusions history of drug addiction and/or blood transfusion and longer duration of hd treatment were the main risk factors determining the prevalence of hcv infection in the hormozgan province of southern iran in 2015. however, the values observed in the present investigation reflect the effective management techniques imposed by healthcare authorities and relevant organizations in recent ye...

background hepatitis a virus (hav) and hepatitis e virus (hev) are both transmitted by the fecal-oral route and are known as the leading causes of acute viral hepatitis in the world, especially in developing countries. there is a lack of updated data on hav and hev seroprevalence in iran. objectives the aim of this study was to determine the seroprevalence of hav and hev among a group of blood ...

Adaptive-like expansions of natural killer (NK) cell subsets are known to occur in response to human cytomegalovirus (CMV) infection. These expansions are typically made up of NKG2C+ NK cells with particular killer-cell immunoglobulin-like receptor (KIR) expression patterns. Such NK cell expansion patterns are also seen in patients with viral hepatitis infection. Yet, it is not known if the vir...

The secondary structures proposed for the cis-acting hepatitis delta virus (HDV) ribozymes contain four duplex regions, three sequences joining the duplexes and two hairpin loops. The core and active site of the ribozyme could be formed by portions of the joining sequences, J1/4 and J4/2, together with one of the hairpin loops, L3. To establish the core region and define essential bases within ...

In elucidating function of two important single-stranded regions [SSrA (726-731 nt) and SSrB (762-766 nt)] derived mainly from three secondary structure models in genomic hepatitis delta virus (HDV) ribozyme possessing self-cleavage activity, we have constructed several random mutants at those two regions on the HDV88 molecule (683-770 nt) by oligonucleotide-directed mutagenesis. When self-clea...
